I was thinking about madness while working on a project for Dungeon World. I have a cursed item that causes the wielder to slowly go insane. I want that to be a tangible mechanic, so I am going to make madness an amount that accumulates over time. My question to you is, should the maximum sanity a person has be equal to their Intelligence stat or their Wisdom stat? I plan on making a Get A Hold of Yourself move that functions like Last Breath but for when your madness would exceed your sanity (since you would essentially lose control of your character after you go insane) and I plan on it being a +WIS roll. For some reason I feel Intellect better represents a person’s capability for logical thought over allowing themselves to be driven insane, but WIS is used for mental fortitude when you use Defy Danger. See my dilemma?
Any suggestions are welcome =)
